Coming from a MAC, and still have a few
I can see and understand the comments of the OP.
1. Inconsistencies in experience - it still annoys me to have two very different browsers, one note, mail, people etc. Sure Windows 10 promises universal apps but it isn't there today.
2. Lack of unified inbox - come on even Outlook on OSX has got one. What is going on here...
3. The keyboard does feel rather low rent, it is also noisy... However typing on it is rather good, but ...
4. The trackpad sucks, no other way about it. It is seriously rubbish. It is ok for me for emergencies, but I'm actually carrying a separate mouse with me.
But despite that, I'm loving the hybrid nature of the device. It is great in daily use and is my primary machine.
